Ive seen these bots for crash games before and they are not guaranteed to win everytime as it is gambling and there is risk involved with everytime you play.
I don't always go for gambling bots because they are not reliable and inaccurate in prediction but what I really like about they platform is the deposits bonus which is base on 3% daily so it will depends on the amount you deposit to determine what you receive as bonus which is use to place bet.
